Introduction to energy tracking Content and compatibility 04 2. Introduction to energy tracking The Kalhuohfummi provides portable power for a large range of mobile electronic devices, including smartphones, tablets, portable GPS systems and portable game consoles. The electrical energy that comes through the Maroshi panel is stored in the battery, and can then be used to charge your devices anyplace, anytime. The Kalhuohfummi is engineered to do considerably more than just store energy. It can accurately tell you how much solar power you are generating, how much you have stored up, and keeps a constant log of both your energy production and CO 2 savings. When connected to our community at www.changers.com, the Kalhuohfummi becomes the portal to our system of awards and rewards. Once you have created an account on our website, simply connect the device via USB, track your savings and start sharing your information. 3.

Controls and connections 06 Battery level indicator The current battery level (see Figure 1) is indicated by four LEDs, which are read from left to right. 4.2 Indicators A B C D Figure 1 The horizontal energy display has three different functions. It shows: 1. The actual battery condition after pressing the button (see table 1). They read from left to right and have the following values: Battery condition Battery capacity A B C D Insufficient energy to charge device Up to 30% Up to 60% Up to 90% >90 % Table 1 Key: shines off 2. The power that supplies the solar module to the Kalhouohfummi. The number of blinks per second shows how many watts of electricity you produce (for example 2 blinks per second means 2 watts power of the solar module). In general, the higher the flash frequency, the more power that is generated by the solar module. Below a power of 1/3 watt LEDs flashes constantly once every three seconds. Depending on the battery capacity the corresponding LEDs will show the charge power (see table 2).

Four steps to solar sharing 08 5. Four steps to solar sharing Ready to get started? Four simple steps make up the Changers system produce energy, measure energy, consume energy and share energy information. In principle, it is possible to connect any solar module that meets the technical specifications in Chapter 7 to the battery. However, we recommend the use of Changers solar panels. 5.1 Generating solar power Plug the DC plug of the solar module into the SUN input jack. Make sure that the solar module is securely mounted by the included suction cups or other tools. Set up your solar panel for optimal solar charging. As soon as sufficient light falls on the solar module, the horizontal energy display will begin to flash green. Watching the blinking frequency of the status display will let you calibrate the best position for your panel. Faster blinking means more energy, so change the angle of your panel for optimum power. Your Kalhuohfummi constantly measures the power generated by the Maroshi solar module, and stores these values internally. The memory contains the last 1000 values of the solar-energy collector. 5.2 Tracking solar power When these values are uploaded to the Changers.com community, the CO 2 savings and the amount of energy produced are displayed graphically for easy reference. This information is then saved, and added to your user profile. With the Kalhuohfummi you can charge a large selection of mobile devices game consoles, phones, tablets and music players, given they have a USB based charging standard and fit one of the included adapters. Each of the included adapters is suitable for a different device. 5.3 Using solar power Before you begin charging, ensure that the device has a suitable charging voltage for a 5 volt supply. Too high electric voltage will cause damage. Connect the USB charging cable to the POWER OUT port of the Kalhuohfummi. Connect the device with the USB cable to begin charging. If in the rare case it is not recognized, please reactivate the output manually by briefly pressing the status button. The intelligent charging electronics makes it possible to simultaneously charge your Kalhuohfummi and your mobile device. For some devices, such as the apple iphone and various navigation systems, please use the cable supplied by the manufacturer. Make sure the connectors match the specifications (see Chapter 7, Technical Data). The compatibility may not always be completely guaranteed.

Care and maintenance 10 7. Care and maintenance a little goes a long way The Kalhuohfummi is robust, tough and easy to clean. However, like every device with a rechargeable Li-Ion battery, there are several things you can do to ensure efficiency and reliability. Before you contact our customer service team, please ensure you read the notes in Chapter 8 about the care and operation of your device. Remember, the Kalhuohfummi is a battery. Prolonged exposure to direct sunlight may cause overheating. Protect the device against vibrations and shock. Keep it free from dust and moisture and ensure it does not overheat. Place no flammable, explosive or dangerous objects in the vicinity of the device. Never attempt to open the device or repair it yourself. Protect the device from rain, humidity and do not place it in liquids. Use the device only at a temperature of 20 C ( 4 F) to + 60 C (140 F). If the Charger is not in use, disconnect all cables. 7.1 Safety guidelines Your Kalhuohfummi stores its energy in rechargeable Lithium-Ion batteries. Their capacity is measured in Wh (Watt-hours.) Over time these batteries naturally lose their maximum recharging capacity. Following the guidelines below will ensure a long life of happy, efficient charging for your batteries. 7.2 General guidelines for Lithium-Ion batteries The battery should never be exposed to temperatures above +60 C (140 F). The optimal ambient temperature is between 0 C to + 40 C (32 F to 104 F). Any prolonged storage of the battery should be done with a battery charge of about 50% (equivalent to two or three LEDs on the display). Failure to do so can result in deep battery self-discharge, which can damage the battery cells. Note the disposal instructions of batteries! (see Chapter 9, Disposal)
Care and maintenance 11 Battery protection system. The Kalhuohfummi comes equipped with an electronic system which protects the battery against surfeit load. An intelligently designed circuit means that even if the power is exhausted, the device will not enter a state of deep discharge. This prevents potential damage to the batteries. 7.3 Tips for usage and handling of the Kalhuohfummi system Solar power battery without charge. If you are unable to load the Kalhuohfummi with solar power and want to prevent a deep discharge, you can simply charge the battery with a conventional charger. For this purpose, you can substitute a Universal Charger with a voltage range from 5 V to 30 V and a current rating of minimum 1 A. Recharging an almost discharged battery. Connect the device via the USB charging cable to your computer or connect it to your panel in the sun. Allow some time to restore you battery to its original state. Use a soft cloth only when cleaning the case of the device. Do not use harsh chemicals, strong detergents or alcohol based products. 7.4 Cleaning
Error handling and customer service 12 8. Just in case: Error handling and customer service If the temperature is too high, this will be shown by the status indicator flashing red/green every two seconds. Remove the device from the source of heat and put it somewhere cool until the light stops flashing. If the temperature of the device is too low this will also be shown by the indicator flashing red/green every two seconds. In this case, move the device to a warm place and wait until the status light stops flashing. Using an alternative solar module may lead to too high voltage (> 30 V). The status indicator will alternately flash red and green every two seconds. If this occurs, please change the solar panel. Before contacting our customer service, please check the links between the Kalhuohfummi and Maroshi devices, to ensure that the problem does not lie there. 8.1 Error handling Answers to frequently asked questions can be found on our website www.changers.com.
